BLADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 767,695, dated August16, 1904.

Application filed December 10, 1903. Serial No. 18 L572. (N0 model.)

To all whom, it may concern.-

Be it known that I, O'rro KAMPFE, a citizen of the United States,residing in the borough of Brooklyn, county of Kings, State of New York,have invented certain new and useful Improvements in Blade-Holders, ofwhich the following is a specification.

My invention relates to improvements in holders for blades or othersimilar devices and is illustrated in its preferred form in theaccompanying drawings, in which similar reference-letters refer tocorrespondingparts.

In the drawings, Figure 1 is a side view, Fig. 2 a back view, and Fig. 3a cross-sectional view, of a construction embodying said preferred form.I

A represents the blade-holder proper,which, as shown, is comprised oftwo parts, a back (0 and sides a. series of slots 6, which are shown assubstantially elliptical in shape and which should each be of greaterextent in the direction running across the back than in the direction ofthe longitudinal axis of said back. These slots, as shown, are arrangedat an angle of substantially forty-five (45 degrees to the longitudinalaxis of said back; but this angle may be Varied somewhat. The sideportions ct are shown as provided each with two lugs or extensions aeach of which is preferably provided with an aperture 12. Preferably theback portion and side portions and lugs will be integral, as shown inthe drawings, and the lugs will be formedby cutting away to a greater orless extent the central part of the side portions. By choice thecut-away portion will be in a curved form, as shown.

The slotst and the apertures I), as above described, give additionalresiliency to the metal both of the back and side portions of theblade-holder. The arrangement of the slots 6 at an angle less than aright angle to the longitudinal axis of the said back entirely does awaywith or at least materially lessens any danger of the strop being tornor scratched The back a is provided with av or cut as the back of saidblade-holder is moved along the same. The shape of the slots, as alreadydescribed, adds still further to the carrying out of this object.

What I claim as new is 1. The combination with a blade-holder of aplurality of slots arranged on the back of said blade-holder and at anangle of less than ninety (90) degrees to'the longitudinal axis thereof.

2. The combination with a blade-holder of a plurality of slots arrangedon the back of said holdersaid slots being of greater extent in thedirection in which they run across the back of said holder than in thedirection of the longitudinal axis thereof.

3. The combination with a blade-holder of a plurality of slots arrangedon the back of said blade-holder and at an angle of less than ninety(90) degrees to the longitudinal axis thereofsaid slots being of greaterextent in the direction in which they run across the back of said holderthan in the direction of the longitudinal axis thereof.

4. The combination with a blade-holder of a plurality of slots arrangedon the back of said blade-holder at an angle of less than ninety (90)degrees to the longitudinal axis thereof, and side pieces connected tosaid back and each provided with an aperture therein.

5. A blade-holder comprising a back portion and side portions-the sideportions hav- .ing the central part thereof cut away to form one lug ateach end.

6. A blade-holder comprising a back portion and side portions, and lugsformed one at each end and provided with an opening in each lug.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

OTTO KAMPFE.
